Carbon Steel Balls

Carbon alloy balls are available in the following types:

Low Carbon Steel Balls (case hardened)

The main feature of this ball is the carburised case with a soft core. This design lends resistance to shock loads and surface wear while providing good load carrying ability. Balls of this type are generally used in applications where there are only moderate loads and slow rotating parts.

High Carbon Steel Balls (through hardened)

Balls of this material have the advantage of being through hardened and will take higher loads and provide longer life than case hardened balls, for such applications as the cycle industry. These balls are substantially cheaper than balls manufactured from high carbon chrome alloy steels.
